So, what is Swim It?

You’ve probably guessed from the name. Swim It is a virtual challenge that encourages you to brave the waves to raise money for Macmillan. It’s a brilliant way to help people living with cancer, while getting active along the way. And the best bit about this virtual challenge? You set all the rules. How far you want to go, how long it’ll take, even your choice of stroke. (Respect to all you butterfliers out there!)

We’ve made the challenge super easy to get involved in. Just pick a start date and set your distance, timeframe and swimming location. It really is that simple. And while you may be the one going the distance, we’ll be cheering you on, providing top tips and key progress updates along the way, so you’ll always feel part of a team.
